[英国《原子新闻》1988年7月第322期报道]当里原型快堆在上个月创造了新的世界纪录。这是世界第一个大反应堆突破了20％的燃耗大关—也就是说燃料中每五个原子中就有一个已分裂或者说已裂变。目前,多数反应堆只达到3％燃耗,而快堆的效率要高得多。由于从燃料中提取了那么多额外能量,如进行再循环,所得能量将较原始铀高60倍以上。英国原型快中子反应堆(PFR)的运行实绩现已接近设计目标的三倍。并使燃料循 [Atomic News, 1988, Issue 322, July 1988] The prototype fast reactor created a new world record last month. This is the world’s first large reactor that breaks the 20% fuel burn threshold—that is, one out of every five atoms in the fuel has split or fissioned. At present, most reactors only reach 3% fuel consumption, and the efficiency of fast reactors is much higher. As much extra energy is extracted from the fuel, such as recycling, the resulting energy will be more than 60 times higher than the original uranium. The performance of the British prototype fast neutron reactor (PFR) is now nearly three times the design goal. And fuel circulation
